【摘要】 通过不同工况滚动轴承振动信号的时序分析，发现其GREEN函数Gj的曲线都是衰减的或收敛的，且衰减速度取决于滚动轴承的运转状态、本文提出的一种新的参数G10可以定量反映其收敛速度。作为滚动轴承的故障诊断指标．参数C10比Kv和NRSS更有效。更多还原

【Abstract】 Through a sequence analysis of ball bearing vibration signals under variousconditions, the curve of parameter Gj, GREEN function, is found to be convergent and theconvergent rate changes with the working condition. A new parameter, G10, is put forwardhere for the first time, which describes the change quantitatively. Using G10 as an index formonitoring the working condition of a ball bearing shows more effective than parameters Kvand NRSS.更多还原
